Risk Of A Diversified Portfolio

The idea of “risk” is used in many fields and industries. There has been large efforts made towards the understanding of risk. Since, risk varies so much depending on the field of study, the need for learning about it is warranted. As can be imagined, the importance of risk in a market economy is crucial. In the 1990s, JP Morgan made the Value at Risk (VaR) a central component of its work efforts (Cecilia-Nicoleta, Anne-Marie, & Carmen-Maria, 2011).

Systematic risk or market risk is the risk that affects a large number of assets. Examples of systematic risk are inflation or increasing the interest rate, or any uncertainties in the economy but not the company 's performance. Unsystematic risk is the risk that mainly associated with specific companies or may be some competitors and suppliers. The systematic risk affects the whole market and cannot be controlled by investors. Unsystematic risk however affects the company and is controlled by the company 's performance. When investors invest money into a company they must research all aspects of that company so they are aware of the unsystematic risks they may encounter.

Nearly all investors look to beta as a way of feeling out the risk of a stock or fund. Put simply, beta measures volatility, or the tendency to swing up and down, as compared to a benchmark. Fund managers that take a bullish stance on the short-term horizon may actively stock up on high-beta equities to drive up returns. Controlling beta becomes an obsession for managers; and after they get the balance just right, they feel confident and reassured in their risk profile. Menchero, Nagy, and Singh concentrate on three estimates of beta to test the accuracy of the measure overall. The first, naive beta, makes a gross simplification that all stocks have a beta of 1. Second, the historical beta can be computed by comparing stock

CAPM results can be compared to the best expected rate of return that investor can possibly earn in other investments with similar risks, which is the cost of capital. Under the CAPM, the market portfolio is a well-diversified, efficient portfolio representing the non-diversifiable risk in the economy. Therefore, investments have similar risk if they have the same sensitivity to market risk, as measured by their beta with the market portfolio.

Equity Risk: The risk of investing in the equity markets as opposed to investing in risk-free investment

Market risk is the risk of potential loss in value of investment and other asset liability portfolios, including financial instruments, caused by changes in market variables, such as interest and currency exchange rates and equity and commodity prices. GE is exposed to market risk in the normal course of business operations as a result of ongoing investing and funding activities.

Furthermore, business risk is the possibility a company will have lower than anticipated profits or experience a loss rather than taking a profit (Business Risk, 2015). Business risk is affected by several factors including competition, input costs, sales volume, economic changes and government regulations. In addition to operating leverage, financial leverage and business risk, financial risk must also be considered. Financial risk is the possibility that shareholders will lose money when they invest in a company that has debt, if the company's cash flow proves inadequate to meet its financial obligations (Financial Risk, 2004). A firm that operates

To find the asset Beta (βa), we need to find the weighted average β of equity and the weighted average β of debt. We consider the β of debt to be 0, as debt has no relationship with market risk and it is evident from the balance sheet that Ameritrade had no interest bearing debt in 1997[1].

As indicated by the case study S&P 500 index was use as a measure of the total return for the stock market. Our standard deviation of the total return was used as a one measure of the risk of an individual stock. Also betas for individual stocks are determined by simple linear regression. The variables were: total return for the stock as the dependent variable and independent variable is the total return for the stock. Since the descriptive statistics were a lot, only the necessary data was selected (below table.)

Diversification of an investment is essential and highly beneficial for a number of reasons. It is used to reduce risk and increase returns by diversifying investments into a number of different areas. Through diversification the effects of business risk or unsystematic risk are dispersed causing investment fluctuations to counterbalance one another reducing risk (Investopedia, 2003). Since the future is unpredictable, investors have no way of knowing with certainty which investments classes will perform the best. By diversifying assets that are uncorrelated with one another an investor can reduce risk and create an investment mix that will provide an increased advantage for high returns.

Financial risk is a major concern world-wide and there are numerous studies to support the necessity to investigate it. Lee (2006)

Undiversifiable –This type of risk is commonly known as systematic or market risk. This risk is associated with each and every company. Causes are things like inflation ray, exchange ray, political instability, entrust rate. This type of risk is not specific to a particular company or industry and it cannot be eliminated or reduced through diversification, its just a type of a risk that investors must accept.

In their research study, Souder & Myles (2010) identify that risk is chiefly fundamental to investing. Böhringer & Löschel (2008) further add that there is no discussion of returns or performance that is deemed meaningful in the absence of at least some mention of the involved risk. However, the trouble for investors, who have just entered into the marketplace, involves the process of figuring where risk really lies, as well as what the difference between the various levels of risks. Relating to the manner, in which risk is fundamental to investments, a significant number of new
